Installation of a new exhaust system may change your motorcycles fuel-air mixture. Please consult the exhaust manufacturer directly with questions regarding any modifications that may be made during, or after, installing their product. If a jet kit or Power Commander is recommended, see the Intake/Fuel section.

Exhaust discoloration (bluing) is caused by engine conditions such as cam timing, fuel-air mixture, operating temperature, etc. It is not the result of defective manufacturing, therefore is not covered by any warranty. See Chems/Lubes section for products to help remove or prevent exhaust discoloration.

Fit great on my kz650, bike runs better and feels a bit faster. Sounds a bit better too. Quality is awful though, welds began to rust a week after installation the first time they got some rain on them.

Installed on a '76 Honda CB550 and it went on fairly easy, and the finish does look really nice! Only gripes so far is that the center stand bracket didn't really work out. Which wasn't a huge problem because with the old 4 into 4 system gone it kinda looked out of place. Though on my bike it is easy to just slide it back on whenever I need to service it.The finish around the collector welds looks like it might flash rust if it were to get caught in some rain.

The sound of the exhaust is great though! Makes my old honda sound like a sport bike. It's definitely louder than stock on acceleration but usually mellows out at cruising speeds.

I'm pretty pleased with it overall, definitely cleaned up the look of the bike!

I really wanted a Performance Header that I could wrap and use any muffler I want. I can do that still. This muffler is a little whiney. Not Beefy! I'm gonna stick a Cherry Bomb on this Header!!! Very Shiny for sure! Nice upgrade. Still doing power/speed tests. I'm getting ready to Pod and Jet!

Had to lift the front of the engine to wiggle the tabs into place.Not that hard to install. Yes, you can do it.

Thank you for having the parts for my 77 Honda 750 K.. I just bought this bike last month and it's in need of a lot of parts... I have been looking for day for the exhaust system, thank you for having it.. This will be my first purchase for fixing up my bike... Matt

P.S. I will let all my friends know of your site, this will save them a lot of time... Thank you....
